Delta Forth .NET

The information in this article applies to:
	Delta Forth .NET 1.31
----

SYMPTOMS:
DO-LOOP structure behaves incorrectly.
The following Forth code:

:MAIN 5 0 DO I . SPACE LOOP;

should print 0 1 2 3 4 but instead it prints 0 1 2 3 4 5.

The same applies for the step loop version (+LOOP).

CAUSE:
DO-LOOP index was not decremented by 1.

STATUS:
Fixed in version 1.4

I am a software engineer based in Timișoara, Romania and currently hold the position of software architect for one of the largest companies in the world.

I invented a dialect of the Forth programming language and implemented the first Forth compiler for the .NET platform. I reverse-engineered the communication protocol of some GPS trackers and wrote from scratch a vehicle tracking system that is currently used to track my two cars. I hold a PhD in computer science and I am the author of several papers and a book chapter. In the 90s I wrote several computer viruses in assembly language for my own research and I was the first to devise a technique to deter heuristic virus scanners. In short, a humble man.
